Totally worked for mine! I almost gave up on it after seeing the YouTube video of the guy smashing his with a hammer. In addition I used a little bit of stablilant 22 contact enhancer product. Thanks Frank!

I can easily find a 185mAh battery but not a 350mAh. Not sure if anyone knows why its shrunk?

185 seems to work fine though.

Great guide. Sooooo easy. - Reply

I’m just wondering the same thing : why is there only 185 mAh batteries, with the same model number, and no 350 mAh available online

I have the Flir One Pro for Android with the same issue. I can’t figure out how to open it. I have an opening tool and there two plastic corners on the top connector face that come out. I can’t figure out how to get it open like you have.
